Based on patented innovations, the Drager PIR 7200 combines maximum light-efficient optics with a signal-stabilising 4 beam technology. The double-compensating optical system is highly resistant to interference from dust, dirt, fog, or other external effects on the optical surface. Due to its non-imaging nature, the measuring signal of the Drager PIR 7200 is unaffected by partial beam block, this ensures immunity from false alarm.

Maximum reliability – SIL 2 Capable!

The Drager PIR 7200 was developed and produced in accordance with SIL standards EN 61508 and EN 50402. For the first time ever, the software of a gas detection device was also assessed – the excellent parameters detailed in the SIL 2 Capable issued by the German TÜV confirm the high product quality and reliability of the Drager PIR 7200: Only two percent of a SIL 2 budget are utilised by the Drager PIR 7200, leaving great flexibility in the selection of control and other system components. The Drager PIR 7200 therefore not only meets the SIL 2 requirements but far surpasses them.

Fast response mode

The sooner a measurable gas concentration is indicated, the faster counter measures can be initiated. The configurable response mode of the Drager PIR 7200 can be set to "fast" for this purpose. In this mode, each measurable gas concentration is indicated within one second. In conjunction with low alarm thresholds, the gas transmitter can contribute to significantly reducing reaction times in the case of an emergency.

Multiple configuration capabilities

The optimum default settings of the Drager PIR 7200 are based on many years of experience. In addition, the PIR 7200 provides the option of user configurable parameters based on customer or application demands. Increased or reduced measuring range as well as configurable special signals (for fault, beam block warning and maintenance) provides maximum flexibility.
